IMPROVEMENT IN SPINDLE-BOLSTERS.

Specification forming part of Letters Patent No. 168,644, dated October11, 1875; application filed September 5, 1874.

To all whom it may concern:

Be it known that I, WELCOME JENoKEs, of Manchester, in the county ofHillsborough and State of New Hampshire, have invented a new and usefulImprovement in Spindle- Bolsters, of which the following is aspecification:

This invention relates to what is known as the spindle-bolster ofspinning-frames; and consists of a longitudinal slot in the bolster, inwhich slot is placed a packing, which is saturated with oil forlubricating the spindle.

In the accompanying drawing, Figure 1 is a side view of the bolster,showing the longitudinal slot. Fig. 2 is a longitudinal section of Fig.1, taken on the line a: 00. Fig. 3 is a top view.

Similar letters of reference indicate corresponding parts.

The bolster is placed in the rail of the spin hing-frame, to support andact as a box for the spindle.

A is the bolster, which is placed in the rail, so that the shoulder Brests on the rail. This shoulder may be nearer the upper end of thebolster, if desired.

In this example of my invention the shoulder is the lower edge of aring, which is formed on the bolster. The said ring covers the upperportion of the longitudinal slot.

0 is the slot in the bolster, designed to be concealed by the rail. Whenthe shoulder B is made nearer the upper end the slot is made shorter, asthe rail covers but about one inch of the surface of the bolster.

For lubricating the spindle, the slot is filled with a fibrous ortextile packing, preferably thick felt, which is cut by means ofproperlyconstructed dies to fit the slot in all its parts. This packingis held in place by the rail, and is saturated with oil from the hole D.(See Fig. 3.) This packing is not allowed to hug or create friction onthe spindle. The oil will be conducted by the loose fibers of thepacking, and keep the spindle sufficiently lubricntcd for a long time. Afew drops of oil introduced through the hole D will be absorbed directlyby the packing, and will keep the spindle lubricated for Weeks, Wherethe ordinary spindle-bolster requires a supply of oil every day.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A spinning-frame spindle-bolster, A, providcd with anelongated open slot, 0, extending up within the bolster ring or shoulderB, and connecting with a passage, D, through said ring, all constructedsubstantially as set forth, for the purpose specified.

WELCOME JEN'OKES.
